Abstract: Using simulation for analyzing the MPLS network is a valid approach. This paper studies the MPLS technology based on ATM, implements the simulation model of the label switch router based on ATM after referring to the MPLS model in the OPNET simulation tools, and constructs the MPLS simulation model. The performance of the data transmission in the experimental network that uses the MPLS model is superior to the network that does not use MPLS. The development of the model benefits the study of the performance of MPLS network.

Key words: ATM, multi protocol label switch(MPLS), simulation model

摘要：

利用计算机仿真分析MPLS网络的性能是深入研究MPLS技术的有效途径。该文通过分析基于ATM的MPLS技术，在借鉴OPNET仿真软件中MPLS模型的基础上，实现了基于ATM的标签交换路由器模型，构建了基于ATM的MPLS网络仿真模型。利用该仿真模型建立的MPLS仿真试验网络，数据传输性能明显优于非MPLS网络。该模型的开发对于MPLS网络的性能分析具有一定的意义。
